2、 良 中 差 建议： 一：确认事物的句型（1）- Are these.?【课文应用】 Are these carrots?这些是胡萝卜吗？ they are.是的,它们是。【句型结构】问句: Are these+可数名词复数?答语: Yes, they are. / No, they arent.【重点解析】问句用于确认近处的事物,是由be动词are开头的一般疑问句。因为主语 these是复数形式,所以be动词要用are。 these用于指代近处的事物，如果想确认远处的事物，要用those。注意问句中的 these在答语中要用they来指代。【生活实例】Jeff第一次去Jim家的农场玩,Jef
